Your`s is the same age as mine & the mileage is nearly identical to mine when I got it.
Can you find out if it has had a new alt,if it`s not had one stands a chance you will sometime soon.Mine went at about 65,000.Does ot have service history?
When you get it check the a/c is blowing cold & the engine fan is switching on/off when it`s on.
Best way to check out alt is to put on all lights ,a/c,radio heated screens,in other words put as much load through it as you can (engine running of course).If the battery light flickers or stays on the the alt will need replacing(ask for a £300 disscount to cover cost of replacement).
Hope this info is of use to you.
Where are you getting it from? If you are going 300 miles that would put you going between 150 & 100 miles north of me.
